The movementMiyota 9039, in plain words
The movement, in plain words
Baltany lists the Miyota 9039 for the S4055 1921 driver watch.
How it runs. An automatic that also winds by hand through the crown. Wearing it keeps it running.
Beat. It beats 28,800 times an hour, 8 a second, so the seconds hand sweeps in small steps.
Off the wrist. It runs for about 42 hours once fully wound. Take it off on Friday evening and it will have stopped by Sunday around midday.
Accuracy. Miyota's figure is -10 to +30 seconds/day.
On your wrist38 mm across, 10.4 mm thick, on a wrist your size
How it sits on your wrist
Set your wrist circumference to compare the 38 mm case with a schematic wrist. The ellipse estimates wrist width and shape. It cannot predict your fit.
17.0 cm6.7 in around
This wrist model is about 56 mm across. The case spans 68% of that estimated width. The lug span ends 6.1 mm inside each model edge.
Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.
How tall it stands
The side view uses listed dimensions. Case shape and lug curve are schematic.
